Abstract
The invention discloses a kind of preparation method of bright pearl so that the making of such bright pearl needs not move through two granulations, the flow dried, the one-shot forming in facility for granulating, and primary drying can obtain the bright pearl of finished product.Moreover, the addition of potassium bichromate has finally played effective buffer action, interpenetrating under aqueous solvent effect between inner core medicine and outer wrapping medicine is prevented, has stabilized the firing property of pearl brightening drug thing.Meanwhile the dissolving common-ion effect based on potassium bichromate Yu other oxides, bright pearl rate of drying made from this kind of method are accelerated；Bright pearls knot structure is more densely cross-linked, and acceptable impulsive force is bigger.It is more preferable to ripple metallic surface passivation living, bright pearl stability based on potassium bichromate；Steady quality, bright pearl quality favourable identity.So the present invention effectively increases bright pearl quality and its stability, it is ensured that firework display effect；Production technology has been simplified, the production cycle has been shortened, reduces potential safety hazard, reduces cost of manufacture.
Description
Technical field
The present invention relates to a kind of bright pearl of fireworks.
Background technology
In fireworks production, firework gunpowder is referred to as bright pearl through being granulated the particulate matter formed.The firework display effect of bright pearl is more
Kind is various.Generally comprise the inner core medicine for producing corresponding effect and mainly act the outer wrapping medicine two parts to ignite.Outer wrapping medicine
Generally ignition charge, the bright pearl outer wrapping medicine of mixed effect include ignition charge and other effect medicines etc. simultaneously.Certain form of cigarette
The bright pearl of Hua Liangzhu, such as red effect, the bright pearl of green glow effect, the bright pearl of blue light effect, the bright pearl of flicker effect, rattle, its inner core medicine
Preferable sintering effect must could be produced using water as solvent-granulation.But outer wrapping medicine is also simultaneously using water as solvent
If, due to the water solubility of oxidant, the component of bright pearl inner core medicine and outer wrapping medicine after shaping interpenetrates, and causes bright pearl to be fired
Put effect variation.
So in practice, in the production of such bright pearl, it is necessary to be divided to two ranks after inner core medicine needed for getting ready and outer wrapping medicine
The bright pearls of Duan Jinhang make：1. in facility for granulating, by the use of water as solvent, pearl processing processed is carried out to inner core medicine, is taken after the completion of pearl processed
Go out, dry, obtain inner core medicine pearl；2. in facility for granulating, with organic solvents such as alcohol, wrapped up in above-mentioned inner core medicine pearl outer surface
Upper outer wrapping medicine, after the completion of take out, dry again, obtain bright pearl finished product.Production process is numerous and diverse, and the production cycle is longer, adds
Potential safety hazard, improve cost of manufacture.
The content of the invention
In order to solve above-mentioned drawback, the technical problem to be solved by the invention is to provide a kind of for the bright of the above-mentioned type
The preparation method of pearl, simplify production technology on the premise of bright pearl effect is ensured, shorten the production cycle, reduce cost of manufacture.For
Solution above-mentioned technical problem, the technical solution adopted by the present invention are a kind of preparation method of bright pearl, comprise the following steps：
The first step, prepare inner core medicine and outer wrapping medicine needed for bright pearl；
Second step, potassium bichromate is added by following proportionings in the inner core medicine and/or outer wrapping medicine：By weight,
The addition of potassium bichromate is the 1~15% of inner core medicine in inner core medicine；The addition of potassium bichromate is outer wrapping in outer wrapping medicine
The 1~15% of medicine；No matter add or be individually added into simultaneously, all according to said ratio.
3rd step, in facility for granulating, using water as solvent, make inner core medicine pearl；
4th step, after inner core medicine pearl completes, outer wrapping medicine is added into facility for granulating, using water as solvent, by outsourcing
Pack is wrapped up in be rolled on the inner core medicine pearl；
5th step, after the parcel for completing outer wrapping medicine, take out wet bright pearl and be dried, get product bright pearl.
Using above-mentioned technical proposal, the making of such bright pearl needs not move through two granulations, the flow dried, in facility for granulating
Interior one-shot forming, primary drying can obtain the bright pearl of finished product.Make moreover, the addition of potassium bichromate has finally played effective isolation
With, prevented between inner core medicine and outer wrapping medicine aqueous solvent effect under interpenetrating, stabilize the burning till property of pearl brightening drug thing
Energy.Meanwhile the dissolving common-ion effect based on potassium bichromate Yu other oxides, bright pearl rate of drying made from this kind of method add
It hurry up；Bright pearls knot structure is more densely cross-linked, and acceptable impulsive force is bigger.Ripple metallic surface passivation living is made based on potassium bichromate
With bright pearl stability is more preferable；Steady quality, bright pearl quality favourable identity.
So the beneficial effects of the present invention are effectively increase bright pearl quality and its stability, it is ensured that firework display effect；
Production technology has been simplified, the production cycle has been shortened, reduces potential safety hazard, reduces cost of manufacture.
Below in conjunction with embodiment, the present invention will be further described.
